Atheists have adopted their opponent's technique and have taken to the streets to spread their belief. Via The Telegraph:

"Organisers originally hoped to put the message on just a handful of London buses, as an antidote to posters put up by religious groups which they claimed were "threatening eternal damnation" to non-believers.
But after the campaign received high-profile support from the prominent atheist Prof Richard Dawkins and the British Humanist Association, the modest £5,500 target was met within minutes and more than £140,000 has now been donated since the launch in October.
Enough money has now been raised to place the message – "There's probably no God. Now stop worrying and enjoy your life" – on 200 bendy buses in the capital for a month, with the first ones taking to the streets .
A further 600 buses carrying the adverts will be seen by passengers and passers-by in cities across England, Wales and Scotland, from Aberdeen and Dundee to York, Coventry, Swansea and Bristol."

There PROBABLY isn't a God? Fucking weak, Atheists. You spend all this money to get your message out and you can't even commit to the definitive "There is no God" statement? Although I believe there is a God, I've always come to admire the passion that Atheists have when they hear that a person is religious. As a matter of fact, Atheists are more in your face about their staunch anti-religious views than religious folks are with their beliefs. This is a totally made up statistic, of course, but it fits into my experiences perfectly so... y'know... eat something phallic. If you're going to believe something enough to broadcast it on so many different types of media, you should at least take the plunge and go all the way with that shit...just saying.

As with the famous Carlsberg ads (‘probably the best lager in the world’), ‘probably’ helps to ensure that our ads will not breach any advertising codes Committee of Advertising Practice advised the campaign that “the inclusion of the word ‘probably’ makes it less likely to cause offence, and therefore be in breach of the Advertising Code.”

Ariane Sherine has said, ‘There’s another reason I’m keen on the “probably”: it means the slogan is more accurate, as even though there’s no scientific evidence at all for God’s existence, it’s also impossible to prove that God doesn’t exist (or that anything doesn’t). As Richard Dawkins states in The God Delusion, saying “there’s no God” is taking a “faith” position. He writes: “Atheists do not have faith; and reason alone could not propel one to total conviction that anything definitely does not exist”. His choice of words in the book is “almost certainly”; but while this is closer to what most atheists believe, “probably” is shorter and catchier, which is helpful for advertising. I also think the word is more lighthearted, and somehow makes the message more positive.’

You could also say “there’s probably no celestial teapot/invisible pink unicorns/flying spaghetti monster/etc” although the probability is so vanishingly small you may as well state that there isn’t. If they HAD been advertising the absence of pink unicorns, I doubt there would have been any fall out, but since it’s this particular issue…

I’m an atheist, and I was a touch disappointed by the message as well. I understand the reasoning, I just don’t agree with it.

UPDATE:

‘Probably’ was included to meet ASA rules. It wasn’t a sop to the masses, it was a technicality!
